Karen - Thank you for your reply and confirmation.
The seeds came from a ripe pod. Seeds are hard and look very similar to other Daylily seeds except for the white color. I only got 4 seeds, but hopefully at least one will produce something lovely. I really like the Siloam doubles, but these white seeds are a first for me. I had no idea, though I do remember someone on the forum mentioning white seeds in a thread somewhere a year or so ago.
Thanks to everyone for your reply to my question.
